Application filed June 20, 1913. Serial No. 774,936.

I '0 all whom it may concern: a slidable top member I workingin a groove Be it known that I, Hnnny FRANCIS KniL, formed in the part B, theitop plece b bea citizen of the United States of America, mg secured in place as by a screw I) adjustable within the show case. The rear plates may be likewise held together as by means of clamps 13 also having a top member: b working in a groove 0 formed in the part B, the top piece I) being secured in place by a screw, b. Strips of felt I) may be inserted between the metal clamps so as to lie between the vertical and horizontal glass plates.

In the use of glass show cases that are made ofplate glass, the various sections of which are clamped together it has been :t'ound, as for example where the cases are frequently moved about, that the clamping devices often work loose after a time as the same bear directly against the smooth face of the glass. In order to remedy this defect and to endeavor to permanently retain the clamping devices in ope 'ati've position orilices are frei' uently bored through the plate glass which and a resident of New York, in the county of New York and State of New York, have invented a certain new and useful Plate-Glass Structure, of which the following is a specification, the same being a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to articles designed for purposes of exhibition, a case or in closure of which all or some of the sides are of glass, intended to keep small and delicate or valuable objects from dust and injury while leaving them in plain sight, and in articular to means for holding the glass plates together by means of metallic corner pieces and of providing the same with means for preventing the same from working loose, which metal pieces may be clamped to the plate glass sides of the show case at the corners thereof, and whereby the plate glass top or cover may be also rigidly and immovably secured to the said show case.

With this object in view the invention consists in certain novel features of con struction and arrangement of parts.

In order to enable the invention to be fully understood, 1 shall proceed to explain the same by reference to the drawings illustrative of one embodiment of the invention, which accompany and form a part of this specification, and in which Figure 1 is a plan view of an article in which my invention is embodied; Fig. 2 is an elevation of the same; and Figs. 3, l, 5,

orifices serve to contain bolts, but this method involves some extra expense and moreover is detrimental to the glass, as the latter becomes so weakened thereby that upon any undue st ain or stress occurring at the point where the hole is located, the glass is apt to become broken, owing to the necessary proximity of the said orifice to the edge of the glass.

In order to overcome these difficulties and to permanently retain the clamping devices in their normal operative positions I make a small indentation a in the glass plate on the inner face of the same, the said indentation being ordinarily curved in contour such (3 and 7 are views in detail showing the conas is ordinarily known as a countersink. I 95 structlon of the various parts of the 111- then insert a screw as C through the clamping device within the show case so that the preferably rounded point of the same will register with and enter the said indentation. The outer part of the clamping device forms a rest or hearing for the glass plate which bearing prevents any undue tension upon the glass when the screw C is operated so that there is broken, while at the same time the said scrnv C rigidly holds the clamping device from working in a lateral direction or from any movement whatsoever. As many indentations a and cooperating screws C may be used as is deemed desirable, and the said clamps may be employed not only in connection with the particular clamping device vention.

Like letters of reference indicate like parts in all the views.

Referring particularly to the drawings which represent a show case which may be of any ordinary or suitable and approved construction, A denotes the front glass plate thereof, A and A the side plates, A the top and A the base of the same, the show case in the present instance being also provided with a wooden back A of ordinary construction.

In order to hold the glass plates together in angular abutment suitable and approved clamping devices may be used such, for example, as the metal corner pieces having no danger of the glass becoming g inch/Z671 shown and described, but also with any plates to register therewith to hold the other of the clamping devices used in conplates from lateral movement, in, combinanection with articles of the character set tion with another corner member the top of forth. which covers the top plate and the lower 5 Although in the embodiment shown the part whereof is flush with the top face of positioning means attached to the clamping the first member, and adjustable means losquare or rectangular show case, yet it is to engage both of the said members whereby, manifest that the invention may be easily by the operation thereof alone, the projec- 10 adapted to show cases of other forms and tions may be forced with an outward prescontours by those skilled in the art. sure against the indentations" in the side desire to be limited to the exact details of side plates with an inward pressure, the construction shown and described, for obpressure being distributed along the faces of 15 vious modifications will occur to persons all of the plates in lieu of being localized.
